ZEROIZING DEVICE FOR CASH REGISTERS 0R CALCULATING MACHINES.

Application filed May 18, 1922.

T 0 all 10710771, it may concern:

Be it known that I, ERNST BREITLING, residing at Essen, Germany, a citizen of the German Republic, have invented a certain new and useful Improvement in Zeroizing Devices for Cash Registers or Calculating Machines, of which the following is a specification.

This invention relates to improvements in cash registers or calculating machines of the kind comprising a plurality of totalizing counters, and it has more. 1 )articularly reference to zero setting devices for such registers or machines.

Now, the invention has for its object to provide a zero setting device for machines of the character stated which is of a construction such as to allow the totalizing counters to be simultaneously set to zero in an operation of the machine following the adjustment of a zero setting member.

The accompanying drawings illustrate, by way of example, an embodiment of the subject-matter of the invention as applied to a cash register comprising a plurality of totalizing counters arranged in a drum.

In the drawings:

Fig. 1 is a side elevation of the drum containing the totalizing counters and provided with the zero setting device;

Fig. 2 is an elevation similar to Fig. 1, the parts being in a different position;

Fig. 3 is a longitudinal section of the drum and the zero setting gearing;

Fig. 4 is a side elevation of the arrangement of the sellers keys and the correspond ing locking members;

Fig. 5 is a view similar to Fig. 4, the parts being in a different position;

Fig. 6 is a side elevation, partially in section, of the special keys for the different lines of business, of the zero setting key and the corresponding locking members;

Fig. 7 is a view similar to Fig. 6, the

parts being in another position;

. Fig. 8 is a section on the line 88 of Fig. 6.

The cash register possesses the usual amount of keys, not shown in the drawing, and is besides provided with a series of sellers keys A (Figs. 4 and 5) and a series of five special keys B (Figs. 6 to 8) for the several lines of business as well as with a zero setting key B arranged above the lastmentioned keys. The totalizing counters C Serial No. 561,900.

are mounted in a drum C Fastened t0 the shaft 0 of every totalizing counter is a zero setting pinion 0 (Figs. 1 to The pinions c are in positive connection with one another inasmuch as all of them are in mesh with a toothed wheel 0 mounted for rota tion on the drum shaft 0*. Two integral toothed wheels (P, d are mounted in the casing wall D (Fig. 3) co-axially with relation to the zero-setting pinion c or one of the totalizing counters. The toothed wheel d is adapted to be coupled with the zero setting pinion 0 by means of two swingingly arranged pinions E which are fastened to a bolt 6 The toothed wheel d is in positive connection with the main driving shaftF of the cash register by means of pinions f f (Figs. 1 and 2). The driving shaft F is provided with a crank handle I. The bolt 6 carrying the coupling pinions E, is mounted in the arm E of a bell crank lever E E the arm E of which is connected by a link 6 to an arm 6 fastened to a shaft 6 Rigidlv connected to the shaft- 6 is another arm E which is provided at its free end with a longitudinal slot 6 which is engaged by a pin g of the nut g of a lock G, which pin lies eccentrically with relation to the axis of rotation of the nut. The coupling pinions E are held in their respective positions by means of a pawl e mounted on the lever arm E and engaging one of the coupling pinions E under the action of a spring 6 A link 6 connects the lever arm E with an arm I2, fastened to a shaft H. The described connection of the bell crank lever E E with the nut g of the lock G and with the shaft H will permit the shaft H to be rocked and the coupling pinions E to be thrown into and out of op erative position by rotating the nut 9 The shaft H carries a locking cam h (Figs. 6 and 7) which is designed to cooperate with a pin 2' fastened to the arm J of a double-armed lever J J which is mounted in the key-bank B The lever arm J is adapted to act on a pin k of a. safety pawl K. The pawl K is fastened to a bolt k A spring 10 connected to the pawl, tends to hold same in engagement with a notch m (Figs. 5 and 7) of a cash register locking lever M which is mounted for oscillation on a shaft m and which, in its locking position, bears against a. locking arm N fastened to the register shaft N. The lever arm J is provided with an oblong-slot 2' which is engaged by a pin 72 of the zero setting key B Each of the special keys B is provided with a pin 1 Provided for cooperation with the zero setting key 3 and the special keys B are a lockin plate P, a locking rocker Q and a slide t. The locking plate P pivoted by one end to a lever m arranged on the m and carrying the locking bar m for the amount keys, while its other end is provided with a slot 29 through which projects a guide pin Z2 arranged on the key bank 13*. The locking plate P is provided with a slot 79 each for the key pin .7 and thekey pins a", the key pin enteringthe respective slot upon a key being depressed. lChe slot 72 for the pin Z2 is positioned with relation to the slots p for the pins 7) in such a manner that, according to the adjustment of the locking plate P, either the zero setting 'key B only or one of the special keys B can be depressed. The locking rocker Q, is swung upwards around the shaft upon depressing a key. It is, in a well-known manner, held in this lifted position, in which it locks the depressed key, until by the striking 01'? a setting disk S 8) against the toe of the depressed key, the movement of this setting disk caused by the operation of the cash register, will be limited, and until the setting in the display and printing mechanism of the line-ot-business mark corresponding to the depressed key caused by the setting disk, has been carried out. The slide R is pivoted by means of a. pin r to the prolongation' m of the cash register locking lever M and guided. by means of its forked end 1 on the shaft 9 @n depressing the key B or a key B, the offset 6 of the key will strike against the slide R so that same will be pressed rearwardly against the shaft The locking lever iii is thereby oscillated around the shaft of, so that it will release the cash 'egister locking arm it. In each operation o1 cash register, one revolution is imparted to the shaft N carrying the locking arm ll Towards the end of this revolution, a projection n of the locking arm N will engage a. roller m mounted on the locking lever M and return the latter into its starting position. latch mounted on a bolt 6 of the'sellers key bankil (Figs. i and 5) and gripping, when in looking position (l), by its hook-shaped end t around the amount key lockingbar 972. serves to hold the bar m against which bear the locking rockers, not shown, of the amount keys. The latch T is securely held in its locking position by alocking cam it which is rigidly -fastened to the shaft H and which is adapted to be placed'in front of a face a of the latch. If the earn 7& takes a position opposite to nave/see of the latch T, the latch is liable ed on the l aft m The lever ries a pin a which engages a slot if of an arm K which is fastened to the bolt k of the pawl K.

The oper ion of the described. arrange ment is as lollows: hen ordinarily operating the cash register for the purpose of registering, the coupling oinions E are held in disengaged position 1) by the lock G being in closing position, and the doublearmed lever J J locked by the locking cam 1? bearing against the pin 15 of the lever, so that the zero setting key B cannot be depressed. The special keys B are also locked until, by the oscillation of the locking bar 027. caused upon setting an amount, the locking plate P pivoted to the arm 29. will be brought into a position such as to cause the slots 79 to be placed in the path of the key pins 5 In these operations of the cash register, the release or the cash register, locking lever M is performed by disengaging the safety pawl K from the notch m of the locking lever M, which disengagement is caused through the intermediary of the prolongation a the pin 25', the bell crank lever U U the pin if, the arm K and the bolt through the locking rocker A being swung upwardly when depressing a sellers key A. At the same time, the latch T has een lifted and the amount key look ing bar m released by the action of the prolongation a on the pin i This movement of the latch T is possible because the locking cam 71. lies oppositely to the recess i (Fig. Now, the amount being set and, thereupon, the cash operating drive released by depressing a special key B, the offset Z) of the key pu es the slide R backward and rocks thereby the released loekir lever M in such a manner that it rcleas the cash register locking arm N When operating the cash register, the totalizing counter 0 corresponding to the depressed sellers key is coupled, for the purpose of registration, w th the amount key setting disks (not shown) while these are being returned to their starting position. i

In order to set the totalizing counters to zero, the lock G is opened. ln doing so, the nut g is turned and a swinging move ment imparted to the arm E which swing ing movement. is transmitted by means of: the shatt 0 the arm 6 and the link 6 to the bell crank lever E E and which causes the coupling pinions E to be brought into engagement with the toothed wheels (Z and 0 At the same time, the shaft H Will be rocked by means of the arm 7L connected through the link to the bell crank lever E in such a manner (Fig. 2) that the locking cam 71, releases the pin 1' and along with same the lever J J as well as the zero setting key B (Fig. 7). Also, the locking cam h' is placed in front of the face t of the latch T, so that the latter is locked in its locking position in which it holds the locking bar m for the amount key locking rockers and the prolongation a of the sellers key locking rocker A The locking plate P, which is pivotally connected to the locking bar m is thus held in a position in which. the zero setting key B but none of the special keys B can be depressed. The release of the cash register locking lever M for the zero set-ting cash register operations takes place in the first part of the movement of depression of the key B the safety pawl K being disengaged from the notch m of the locking lever hi by the action of the arm J of the lever J J on the pin In the further course of the movement of the key B its offset 6 willstrike against the slide R and, in the same manner as afore described with relation to a special key, it will cause the released locking lever M to rock in such a manner as to release the cash register locking arm N There upon, one revolution is imparted to all of the totalizing counter shafts c which are coupled with the cash register driving shaft F through the toothed wheels 0 0 E, (Z (Z f 7, for the purpose of simultaneously setting them to zero. The zero setting cash operation can. also be utilized to set a mark, influenced by the zero setting key, in the display and printing mechanism in a manner such as is well known for setting a sellers mark.
